Larry PY - 2022 T2 - Harrison's Principles of Internal Medicine, 21e AB - Intracranial hemorrhage is a form of stroke (see Chap. 426). Compared to ischemic stroke, patients with intracranial hemorrhage are more likely to present with headache; however, brain imaging is required to distinguish these entities. CT imaging of the head is highly sensitive and specific for intracranial hemorrhage and determines the location(s) of bleeding. Hemorrhages are classified by their location and the underlying vascular pathology. Hemorrhage directly into the brain parenchyma, also known as intracerebral hemorrhage (ICH), and arteriovenous malformations (AVMs) of the brain will be considered here. Other categories of hemorrhage include bleeding into subdural and epidural spaces, usually caused by trauma (Chap 443), and subarachnoid hemorrhage due to trauma or the rupture of an intracranial aneurysm (Chap. 429).
